I'm curious if anyone else was able to make over 400 with a tune, pulleys, exhaust, intake.

Some others have made a bit more full bolt on. I had a pulley and was catless, but had to sell to pay for my grandmothers funeral. When I get back on my feet, I'll do a pulley, air filter and custom xpipe catless exhaust.

But like you said, no one listens. 400whp with just catback and proceed when others need full bolt on and barely make 400.
